The start of the new gameplay trailer sees Ganon raising his army with a mechanic familiar to anyone who has played BOTW: the blood moon. In that game, blood moons caused enemies Link had slain to regenerate, and they appear to have a similar effect here, though things seem way more intense this time around. Flaming projectiles rain down, huge explosions occur, the earth shakes as a castle appears to rise from underground. Possibly, this is just for effect during cutscenes. Then again, Nintendo has to up the ante to make things seem more dramatic in the sequel, so brace yourself for at least some of these things actually happening in-game.
